Froth is a light, bubbly foam that forms on the surface of liquids, often seen in beverages like beer and coffee. It occurs when air is trapped in the liquid, creating tiny bubbles. Froth can enhance the texture and appearance of drinks, making them more appealing. In addition to beverages, froth can also be found in natural settings, such as on the surface of ocean waves or streams. It is often composed of proteins, fats, and other substances that stabilize the bubbles. Froth plays a role in various processes, including the aeration of liquids and the creation of emulsions.
